Examples

The following code example gets a list of installed languages. The example requires that textBox1 has been instantiated and that textBox1.MultiLine has been set to true.

public:
   void GetLanguages()
   {
      // Gets the list of installed languages.
      for each ( InputLanguage^ lang in InputLanguage::InstalledInputLanguages )
      {
         textBox1->Text = String::Concat( textBox1->Text, lang->Culture->EnglishName, "\n" );
      }
   }

public void GetLanguages() {
    // Gets the list of installed languages.
    foreach(InputLanguage lang in InputLanguage.InstalledInputLanguages) {
       textBox1.Text += lang.Culture.EnglishName + '\n';
    }
}

Public Sub GetLanguages()
    ' Gets the list of installed languages.
    Dim lang As InputLanguage
    For Each lang In  InputLanguage.InstalledInputLanguages
        textBox1.Text &= lang.Culture.EnglishName & ControlChars.Cr
    Next lang
End Sub

The next example sets the default input language as the current input language. The example requires that textBox1 has been instantiated and that textBox1.MultiLine has been set to true.

public:
   void SetNewCurrentLanguage()
   {
      
      // Gets the default, and current languages.
      InputLanguage^ myDefaultLanguage = InputLanguage::DefaultInputLanguage;
      InputLanguage^ myCurrentLanguage = InputLanguage::CurrentInputLanguage;
      textBox1->Text = String::Format( "Current input language is: {0}\nDefault input language is: {1}\n",
         myCurrentLanguage->Culture->EnglishName, myDefaultLanguage->Culture->EnglishName );
      
      // Changes the current input language to the default, and prints the new current language.
      InputLanguage::CurrentInputLanguage = myDefaultLanguage;
      textBox1->Text = String::Format( "{0}Current input language is now: {1}",
         textBox1->Text, myDefaultLanguage->Culture->EnglishName );
   }

public void SetNewCurrentLanguage() {
    // Gets the default, and current languages.
    InputLanguage myDefaultLanguage = InputLanguage.DefaultInputLanguage;
    InputLanguage myCurrentLanguage = InputLanguage.CurrentInputLanguage;
    textBox1.Text = "Current input language is: " + myCurrentLanguage.Culture.EnglishName + '\n';
    textBox1.Text += "Default input language is: " + myDefaultLanguage.Culture.EnglishName + '\n';
 
    // Changes the current input language to the default, and prints the new current language.
    InputLanguage.CurrentInputLanguage = myDefaultLanguage;
    textBox1.Text += "Current input language is now: " + myDefaultLanguage.Culture.EnglishName;
}

Public Sub SetNewCurrentLanguage()
    ' Gets the default, and current languages.
    Dim myDefaultLanguage As InputLanguage = InputLanguage.DefaultInputLanguage
    Dim myCurrentLanguage As InputLanguage = InputLanguage.CurrentInputLanguage
    textBox1.Text = "Current input language is: " & _
        myCurrentLanguage.Culture.EnglishName & ControlChars.Cr
        
    textBox1.Text &= "Default input language is: " & _
        myDefaultLanguage.Culture.EnglishName & ControlChars.Cr
    
    ' Changes the current input language to the default, and prints the new current language.
    InputLanguage.CurrentInputLanguage = myDefaultLanguage
    textBox1.Text &= "Current input language is now: " & _
        myDefaultLanguage.Culture.EnglishName
End Sub

Remarks

An input language is a culture/keyboard layout pair that determines how the physical keys on a keyboard map or plot to characters in a language. The input language is based on a Windows input locale identifier, such as that returned by the Platform SDK function, GetKeyboardLayout. The input locale identifier is also called a handle to a keyboard layout (HKL) value.

Use the static methods provided to find all installed mappings of the system and to change the input language for a thread or process. Call CurrentInputLanguage to get the current input language. Call DefaultInputLanguage for the default input language. Call InstalledInputLanguages to get all the installed languages in this system. After you have a list of all the installed languages, use CurrentInputLanguage to change the current input language to a different language.

Properties

Culture	Gets the culture of the current input language.
CurrentInputLanguage	Gets or sets the input language for the current thread.
